N2 and O2 all have a quadrupole&comma; for the reason that the quadrupole of N2&lpar;0&period;31 &angst; &rpar;is bigger than the quadrupole of O2 &lpar;0&period;10 &angst; &rpar;&comma; the adsorption capacity by molecular sieve to N2 is stronger than O2&period; When the compressed air in certain pressure flow through adsorption bed formed by molecular sieve&comma; the N2 gas is absorbed and O2 is obtained by separation&period;

The main part of N2 generator is two towers filled with molecular sieve&comma; when the compressed air get into adsorption tower&comma; the N2&comma; is absorbed by molecular sieve&comma; N2 is produced from the export terminal&period; When one tower produces N2&comma; another tower release the N2 by reducing the pressure to get the renewable desorption of carbon molecular sieve&period; Two towers alternate adsorption and regeneration to output N2 continuously&period;

HUILIN SMT Nitrogen Machine has 5 strongpoints in PSA nitorgen machine field&comma; manufacturing energy-saving nitrogen machine&period;1&period; The purity of N2 could be regulated between 95&percnt; to 99&period;99&percnt; according as users need&semi;2&period; Dryness and low dew point of N2&semi;3&period; Low cost&comma; high return&comma; investment recover soon&semi;4&period; Compact appearance&comma; small area&comma; high purity for satisfying the high requirements of the many kinds of industry&semi;5&period; Mature technology&comma; high-quality accessories&comma; durable product
